What’s the weather like in Marmaris in September?

Marmaris, which is on the Turquoise Coast in southwestern Turkey, has quite typical Mediterranean weather. Temperatures are a bit cooler in September after the summer highs, although you’ll still get lots of hot and sunny weather at this time with not much rain. It’s the perfect time to visit if you’d rather avoid the scorching and busier July and August. Marmaris is in a sheltered bay on the Turkish Riviera, which stops northern and Mediterranean winds from cooling things down too much.


The average high in Marmaris during September is 31ºC, which is perfect for relaxing at the beach. It stays nice and pleasant in the evenings too with things cooling to 17ºC. The sea temperature’s 26ºC, which is fantastic for swimming, while humidity’s moderate. There’s 17mm of rain over four days, and you can expect 12 hours of daylight with 11 hours of sunshine each day. UV levels will be high so remember to pack sun cream. Sunset’s just after 7.30pm at the start of the month.
